Why is my blitz rating so much lower than my rapid rating (and how do I close the gap)?

• On Chess.com and Lichess, your blitz and rapid ratings are calculated separately, so one never pulls the other up or down.
• Chess.com says differences of several hundred points between time controls are very common and that the ratings may stay different even after many games.
• Chess.com estimates game length as base time plus 40 times the increment; Lichess uses the same estimate with its own cutoffs.
• A very large gap is usually a clock problem: losing on time, or moving too fast and missing tactics.
• To narrow it, look at where your blitz games go wrong, use increment before no-increment blitz, and keep a short safety check for checks, captures and threats.

Yes. Chess.com's help center says it is completely normal for Rapid, Blitz and Bullet ratings to differ, that large differences between time controls are very common, and that a difference of several hundred points doesn't necessarily indicate a problem with your account or rating. It also says the ratings may remain quite different even after many games.

Chess.com describes rapid as giving you more time to calculate and think through moves, while blitz rewards quick decision-making and pattern recognition. Being stronger at one is expected.

Both sites decide the category from an estimated game length, not from the base time alone. That is why a 10+0 game counts as rapid while a game with a short base and a large increment can also land in rapid.

Each site has its own pools and labels, so a blitz rating on one site is not directly comparable with the other. Chess.com vs Lichess rating covers the differences between the two sites.

Each time control has its own rating, calculated only from games in that category. Chess.com says your Rapid rating isn't used to determine your Blitz or Bullet rating, and vice versa.

A rating with few games behind it also moves more. Chess.com says that with only a small number of games in a time control, the rating may change more quickly. Lichess uses Glicko-2 and marks a rating provisional with a question mark when a player has not yet finished enough rated games in that category. If you have played much more of one format than the other, the less-played one is the less settled number.

How to analyze your own chess games shows a short review routine you can run on blitz losses.

Build recognition where you have time to think, then practise using it with a little extra time per move before going back to the fastest controls.

1. Keep playing slower games and puzzles. Patterns you have already seen many times are the ones you can find quickly in blitz.
2. Move up to a blitz control with increment, such as 3|2 or 5|3, before playing 3|0. The increment gives back a little time every move.
3. Shrink your thinking routine to the essentials: before moving, look at your opponent's checks, captures and threats.
4. Spend time where the position is sharp, and play quiet or known moves quickly. Chess time management has clock rules.
5. Stop after a losing streak. How to stop tilting in chess covers stop rules.

If you care most about playing well in longer games, your rapid rating may be the better measure of what you are training, and you don't have to chase the blitz number. Blitz or rapid to improve covers which time control to play most if improvement is the goal.

Paraphrased community opinions from an r/chess discussion, not tested methods:

• The two ratings measure different skills, so comparing them directly is misleading.
• Get better at slow chess first, then learn to apply it quickly.
• After each opponent move, ask what their plan is.
• Switching from a no-increment control to one with increment gave more room to think.
• Share a few games so others can see where they go wrong, or simply focus on rapid.
